Danfoss scroll compressors for refrigeration applications The MLZ and LLZ series are purpose-engineered for applications in refrigeration with respectively medium and low temperatures. They suit all operating conditions in different cooling systems. Energy Savings Optimize your system with the scroll compressors for refrigeration. The combination of an energy efficient motor and an optimized scroll wrap for refrigeration applications delivers high efficiency in fixed-speed compressors. Optional vapor injection boosts the cooling capacity and efficiency by more than 20%. Low sound Improve the...

Wide operating envelopes comply with all applications in the refrigeration Boost cooling capacity and efficiency with vapor injection in low temperatures LLZ - R404A / R507 for low temperatures With vapor injection Evaporating temperature (°F) -49 Danfoss proposes the optional activated economizer line kit to boost compressor efficiency and capacity with vapor injection. The system uses a liquid subcooler circuit. During the liquid subcooler process, some liquid refrigerant evaporates in the economizer and is injected into the scroll set at intermediate pressure. This provides additional cooling...
